SASH-FASTENER.

SPECIFICATION forming part of Letters Patent No. 749,469, dated January 12, 1904.

Application filed April 29, 1903.

To all whom it mag concern..-

Be it known that I, ANTENOR AssoRATI, a subject of the King of Italy, and aresident of the borough of Manhattan, in the city and State of New York, have invented a new and useful Sash-Fastener, of which the following is a specification. i

My invention relates to a sash-fastener, with the object in view of providing a simple and efficient fastener which willserve to hold the sashes, one or both of them, partially opened and locked against'further unintentional openrear in the plane of the line A A of Fig. 1 looking toward the right as the drawing is held and showing the sashes locked in their closed adjustment. Fig. 3 is a similar View showing the upper sash lowered one step and the two sashes locked against further opening. Fig. 4 is an enlarged face view in detail of one of the catches and its support. Fig. 5 is a view of the same, showing the support in front elevation and catch in edge elevation.

. point Where the catch is secured.

back view of the support, showing the flange Fig. 6 is a rear view in detail of the catch. Fig. 7 is an edge view of the same. Fig. 8 is a face view of a portion of the support at a Fig. 9 is a to which the catch is connected in edge elevation; and Fig. 10 is a partial section on the line A A of Fig. 1 looking toward the left as the drawing is held and showing in full lines the position of an auxiliary catch for holding the lower sash locked down while permitting the upper sash to rise and fall at pleasure and I in dotted lines the position of the lower sash when slightly raised and locked against further lifting.

The upper sash is denoted by 1, and the lower sash by 2. To the side rail 3 of the up- Serial No. 154:,784. (No model.)

per sash I secure a metallic plate L-shaped in cross-section, the flange 4 of the plate being provided with screw-holes 5 for securing it to the front of the side rail 3 and preferably in proximity to the bottom of the upper sash. While I have shown the plate secured to the side rail 3, I wish it to be understood that it is a mere matter of choice which of the side rails of the upper sash it shall be secured to, as the plates, with their catches, may be made right and left, so as to be secured to either the right or left hand rail, as may be desired. The other flange 6 of this supporting-plate L- shaped in cross-section is provided with a series of pintles 7 in the present instance three, located at such distances apart as may be found desirable for holding the window-Sasha greater or lesser distance open. The number of these pintles may be increased or diminished at pleasure, the number here shown being that which is commonly found desirable in practical use. On each of these pintles 7 I mount a catch 8, preferably having an eccentric semicircular shape with a protruding nose 9, intended as the catch is swung to overlap the adjacent sash.

The catch is provided with a curved recess 10,

on its inner face, as clearly shown in Fig. 6, for the reception of a wide lug 11, struck outwardly from the flange 6 of the supportingplate, and with a hollow recess 12, extending along the margin of the catch to determine the extent of the swinging movement of the catch, the said recess 12 being provided with a rounded tooth 13 in proximity to one end, which serves as a retaining-tooth to hold the catch out of operative position. The tooth or raised portion 13 coacts with a short lug 1 L on the end of a curved arm 15, struck from the flange 6, the latterbeing formed of spring metal, so that the arm 15 will serve as a friction-spring for holding the catch in any position to which it may be swung by the operator. The wide lug 11, working in the recess 10, also serves to limit the swing of the catch, and so prevent any undue strain upon the slender spring-arm 15, which aflords the friction for holding the catch in its adjustments.

In operation, the plate, with its several catches, having been secured in the position shown in Fig. 1, the swinging of the lower catch, as shown in Fig. 2, will serve to lock the two window-sashes securely against movement relative to each other, and so may serve as a window-fastener to hold the windows shut. When it is desired to drop the upper sash a step, the lower catch may be swung back into the position shown in Fig. 3 and the next catch above it swung out into position to catch the top of the lower sash, and this will prevent the upper sash from dropping more than one step and also the lower sash'from rising more than that step, and so the two sashes will be locked in position, so that there can be no opening broader than the distance between the lower catch and the one next above or whether it be at the top of the upper sash or at the bottom of the lower sash. In the same manner by swinging the lower catch out of operative position and also the one next above it out of operative position and the upper catch into operative position the two sashes may be opened a distance of two steps. Where it is desired to fasten the lower sash shut or slightly open while permitting the upper sash to rise and fall at pleasure, I apply an auxiliary support with catches similar to those hereinabove described to the side stop 16 just above the top of the lower sash 2, as shown in Fig. 10.

What I claim is 1. A sash-fastener comprising a support having a perforated flange for securing it to the window-sash and a flange extending at right angles to said perforated flange, a plurality of catches pivoted to said last-named flange and means for exerting friction upon the catches to hold them in their adjustments.

2. The combination with the upper and lower window-sashes, of a series of catches secured in vertical alinement to the upper sash in position to swing over the top of the lower sash and means for holding the catches in clifferent swinging adjustments.

3. The combination with the upper and lower window-sashes, of a series of catches secured in alinement with the upper sash in position to swing over the top of the lower sash, means for holding the catches in their swinging adjustments and a second series of catches secured to the window-frame in position to swing over the top of the lower sash whereby the two sashes may be locked with respect to each other and the lower sash locked independently of the upper sash.

4. The combination with a support formed of spring metal and having an arm struck therefrom, of a recessed catch pivoted to the support in position to cause the free end of the said spring-arm to travel along the recess in the catch and means for securing the said support in proximity to the window-sash.

In testimony that I claim the foregoing as my invention I have signed my name, in presence of two witnesses, this 27th day of April, 1903.
